What do u think about run 2 5830 without OC on a Cooler Master Extreme Power Plus 600w? It is better and cheaper than one 5870 but the problem its the PSU...
My honest opinion? Only worth it if you don't have to pay for electricity. Otherwise you get BTC faster by using PTC (Paid to click) and Task Sites.
I was mining with 2x 5750, which I stopped completely since I found that using a combination of PTC Sites (Bitvisitor, Coin of Midas) and some Task Sites (Coinworker, Tasks4Dollars, Dollarrewardz) for about 2 Hours generates more BTC than mining at 350 MH/s for 24 hours and I don't have to substract the electricity cost from that.
Yes, i know, i love filehosting remoting (remote upload of files and get $$ per download), but, i mine LTC too with 2 7850, and i have another computer for nothing that have this psu, so if I can put 2 5830 in it would be nice for me.
Thanks guys, I'll test it, if it crash, well, bye bye CM (cheaper psu that i have in a pc that not use)...
